Digital imaging guidelines for photographers : Updig (Universal photographic digital imaging guidelines), an ad-hoc industry consortium published 15 guidelines for photographic digital imaging. The guidelines aim to clarify issues affecting accurate reproduction and management of digital image files. Although they largely reflect a photographer’s perspective, anyone working with digital images should find them useful. The guidelines have the following primary goals: First; Digital images look the same as they transfer between devices, platforms and vendors. Second; Digital images are prepared in the correct resolution, at the correct size, for the device(s) on which they will be viewed or printed.
